Where are the biodiversity hotspots in Australia?
The South West Australia Ecoregion (SWAE) is Australia’s only Global Biodiversity Hotspot, and is home to a variety of unique flora and fauna which are under serious threat. In fact, this region has the highest concentration of rare and endangered species in Australia.

Tropical forests are typically biodiversity hotspots and are usually filled with endemic species. The Upper Amazonia/Guyana Shield, the Congo Basin, and the New Guinea/Melanesian Islands have the highest number of endemic terrestrial (land-living) species on Earth [6].
